67This module provides support for <span class="Unix">Unix</span> shell-style wildcards, which
68are <em>not</em> the same as regular expressions (which are documented
69in the <tt class="module"><a href="module-re.html">re</a></tt><a id='l2h-2346' xml:id='l2h-2346'></a> module). The special
70characters used in shell-style wildcards are:

92Note that the filename separator (<code>'/'</code> on <span class="Unix">Unix</span>) is <em>not</em>
93special to this module. See module
94<tt class="module"><a href="module-glob.html">glob</a></tt><a id='l2h-2347' xml:id='l2h-2347'></a> for pathname expansion
95(<tt class="module"><a href="module-glob.html">glob</a></tt> uses <tt class="function">fnmatch()</tt> to match pathname
96segments). Similarly, filenames starting with a period are
97not special for this module, and are matched by the <code>*</code> and
98<code>?</code> patterns.

104<dd>
105Test whether the <var>filename</var> string matches the <var>pattern</var>
106string, returning true or false. If the operating system is
107case-insensitive, then both parameters will be normalized to all
108lower- or upper-case before the comparison is performed. If you
109require a case-sensitive comparison regardless of whether that's
110standard for your operating system, use <tt class="function">fnmatchcase()</tt>
111instead.

129It is the same as <code>[n for n in names if fnmatch(n, pattern)]</code>, but
